, The principal objects of the present inven- `moisture is not added to the coke and in such la `way thatheat is recovered from the coke and in such a way that the coke is notunduly oxidized, and to accomplish the above Y results, if preferred, without the expense of installing pumps or machinery for effecting circulation and consequently with a saving of the power .that would be required for operating such machinery if present.

Another object of the invention is to provide apparatus of the type mentioned which,

if preferred, may be used without power driven moving parts.

Other objects of the invention will appear from the following description at the end of which the invention will be claimed. Generally stated,.the invention may be said to consist in apparatus for cooling coke including a coke wharf or platform and boiler 'n tubes or other boiler elements juxtaposed in confronting heat radiating relation, and ai'- ranged in the saine internally uninterrupted chamber, a casing providing the chamber and of which the walls enclose both the wharf and the tubes, means for introducing incandescent coke into the chamber, means for withdrawing cool coke from the chamber, and steam oiftake provisions.

The invention also comprises the improvements to be presently describedpand kfinally In the following description reference will be made to the accompanying drawings form- `ing part hereof and in which Figure 1 is a side elevation partly in section' illustrating one form of apparatus for cooling coke selected from among other forms for the purpose of describing the invention.

Fig. 2 is a sectional view drawn to an enlarged scale and illustrating the apparatus shown at the central portion of Fig. 1.

Fig. 8 is a sectional view taken generally on the line 8 3 of Fig. 2.

Fig. 4 is a cross-sectional view taken generally on the line 4 4 of Fig. 2.

tion of the coke platform.

FigJ is anenlarged view principally in section illustrating the -louverlike construe-yv i Fig. Gis a perspectivev'iew of one of the wharf plates, and f' Figs. 7, 8 and 9 are respectively'a plan, a side lelevation and anend view Vwith parts broken away illustrating a modification. In thedrawings, referring more particularly to Figs. l to 6, 1 is acoke wharf orplatform and 2 are boiler tubesor elements juxtaposed in confronting relation and arranged l in the same chamber. -3 is acasing providing" a chamber shown as rectangular and'ofIwhich the walls enclose both the wharf and the tubes. As shown the coke wharf 1 is foraminous and it is louverlike.

As shownit consists of-v spaced lapping Wharf plates 4l, Fig. 5, m0unt` ed .upon stools or feet 5 and beveled- "as at 6 where they underlap.- The wharf or platform is shown as inclined from the inlet to the outlet and when it is inclined the feed'isv` affected by gravity. 7 is a frame shownV to consist of lengthwise ranging girders^upon the latterof which the wharf plates are mounted. The frame also provides sideguide walls 8 for the wharf. The wharf is spaced 7 and they overlie the platform 1 andfare Y inclined in the direction of feed. The-boiler tubes 2 may in general be disposed above and below and at the sides of the coke wharf 1 and they connect with steam oiftake provisions 11. 101, Fig. 1, is a water inlet.. In gen- M vided with a hinged lid lihaving flanges 17 vfor cooperation with a water seal 18.*. The

lid is also provided with a guard 19 for protecting the water seal against the admission of coke andY dust. 20 is an olftake hopper provided with two counterweighted hinged gates 21 and 22, the latter preferably providing a water seal.

The casing may be fixed as shown, or it may be portable and it may contain aduplication of coke wharfs and boiler tubes as described.

The mode of operation will be explained in connection with the embodiment illustrated in Figs. 1 to 6 of the drawings in which the apparatus is shown as fixed and arranged to receive hot coke from a car 23 and to deliver cool coke to a convever 24, Fig. 2. However, the charge of colte 25, Fig. 2, may'have been introduced upon the wharf and however it ma)7 be fed through the casing it is juxtaposed in confronting heat radiating relation to the boiler tubes or elements 2 with no separating medium between them, or perhaps more accurately, no substantial separating medium between them because the wharf is foraminous and the side guide walls S are negligible. The baffle plates 10 insure an even distribution of the coke on the platform or wharf 1 and assist in bringing it into the described relation with the boiler tubes. Heat convection currents may develop within the interior of the casing as indicated by arrows but the exchange of heat is essentially effected by heat radiation and without the intervention or assistance of applied power or of moving parts. The louverlike construction of the wharf plates provides the necessary openings through the platform 1 and also prevents the passage of coke through the openings when the coke is fed or permitted to gravitate through the chamber.

The construction and mode of operation of the modification illustrated in Figs. 7 to 9 inclusive are as above described with the following exceptions:

109J is a blower shown as driven b v a motor 103, and the intake of the blower is connected by pipe 104, having a damper 105, with the interior of the casing 3 above the colte wharf 1. The outlet of the blower is connected by pipes 106. having dampers 107, with the interior of the casing below the colte wharf 1. At the sides of the coke wharf 1 are provided valves or shutters 108 adapted to open and close the space 9 and thus establish and disestablish communication from below to above the coke wharf 1 at the sides thereof. These valves or shutters are shown as pivotallv mounted and they may be opened and closed from one end of the apparatus by mechanism 109.

Gases are taken from above the coke wharf 1 and the closed shutters or valves 108 and are returned to below the colte wharf 1 and the closed shutters or valve's 10S, by the blower 102, and its described connections, and thus the gases are recirculated through the coke and through the openings provided through the coke wharf 1. The construction shown in Figs. 7 to 9 may be operated in the manner described in connection with the construction shown in Figs. 1 to 6, by opening the valves or shutters 108, closing the dampers 105 and 107, and stopping the motor 103.

It will be obvious to those skilled in the art to which the invention relates that modifications niay be made in details of construction, arrangement and mere matters of form without departing from the spirit of the invention which is not limited as to those matters or otherwise than as the prior art and the appended claims may require.
